为什么我的ASP.NET程序运行不了

[七伤拳]

我用VS.NET新建一个ASP.NET工程，并没做任务修改，但是运行时却出错，错误信息如下：

Server Error in '/' Application.
--------------------------------------------------------------------------------

Configuration Error

Parser Error Message: It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.

Source Error:

请问这到底是怎么回事？
谢谢了。
